Class
    Foam::FieldActivatedInjection
 
Description
    Injection at specified positions, with the conditions:
 
    For injection to be allowed
      \verbatim
      factor*referenceField[celli] >= thresholdField[celli]
      \endverbatim
      where:
        - \c referenceField is the field used to supply the look-up values
        - \c thresholdField supplies the values beyond which the injection is
            permitted.
 
    Limited to a user-supplied number of injections per injector location
